| Abstract: | Aiming at acquisition of radar moving target full-polarization high resolution information,signal model of wideband polarization radar and corresponding match filter algorithm is established.Meanwhile,window method in time domain and frequency domain is compared and a practical window method is proposed.After that,the performance of moving target polarization measurement through wideband up and down chirp signals is analysed and co-identifying method using both polarization and range profile information is proposed.At last,algorithm validity is proved by computer simulations. |
